I have Oakley and Hissy in the exact same enclosure setup. 19 qt Rubbermaid w/ clamp top, t-rex (I think) UTH wrapped in aluminum foil (after looking at the 10 gallon tank setup thread), aspen bedding, 2 hides, 1 water bowl, dimmer, accurite thermometer w/ probe on bottom of tub on top of UTH.

So here is my issue, both of the temps are different and neither are holding humidity well. I measured the surface temp on the hot side of Hissy's cage w/ my temp gun last night and it was 91, measured Oakley's, 83. The humidity is also staying in the low 50's and I am trying to get Oakley's up because he is soon to shed but it won't stay up. It gets to a max of about 60% and will drop. I had holes in it but I had to cover them back up because of the low humidity. I am also having an issue with having to turn up the dimmers too high to get the temps right on top of the substrate but neither of them are burrowing down so I don't guess that is too much of a problem. I have taken out LOADS of aspen to get the depth right, it's about 1" deep right now I think. I hooked up Oakley's UTH to Hissy's dimmer to see if that helps but I didn't have a chance to check it this morning but I'm not sure if it is helping.

Any ideas?
